Over 85 people are reported to have died from the flu so far this winter with different strains dubbed French Flu and Japanese Flu also said to be spreading.

Heather Teale, the mother of the Scottish teen who died when the bug turned to pneumonia, took to social media to confirm the news and pay tribute to her daughter.

Writing on Facebook the day after Bethany passed away, Ms Teale said: “My beautiful Daughter Bethany Walker was taken from me yesterday.

The flu heatmap from flusurvey.org.uk - The map shows a gradient from no reported ILI (blue) to very high ILI (red).

“She had been suffering from a flu virus, which became pneumonia, she was airlifted to Raigmore with me by her side yesterday morning, where she rapidly deteriorated, the staff in Intensive Care could not have done more.

“She was given the best possible treatment from a team of eight people for over two hours, they tried everything possible but sadly despite their best efforts she didn’t make it. I am broken, the bottom has fallen out of my world.

“I have my mum with me, and my wonderful son who are both feeling the same loss as I am. Life will never be the same again.

“Bethany, I love you to the moon and back, I always have and I always will, you were the best Daughter I could have ever wished for and I will always be the proudest Mum in the world. “I have no more words. I’m truly devastated. Sleep tight my beautiful girl, your brother and I will love you forever, you will never be out of my thoughts as long as I live.”
